Overview
- Three people were killed in the May 18 mosque shooting at the Islamic Center of San Diego and the two suspected gunmen later died by suicide, establishing the deadly incident that prompted this legal action.
- The Vazquez parents filed a lawsuit at the end of August alleging their 18-year-old son left a Park Mental Health residential site the night before the attack and that staff showed them surveillance of him leaving and told them to wait 24 hours before filing a missing-person report.
- Park Mental Health has said the lawsuit contains factual errors, stressed that its program is voluntary and outpatient and that it cannot lock or detain clients, and has disputed that it had the authority to restrain the teen.
- The complaint adds that the FBI warned the family days before the shooting about the teen’s dark-web contacts discussing school shootings and suicide, and it cites earlier school reports and a 2025 gun-violence restraining order as prior warning signs.
- Separately, prosecutors in North Carolina have indicted a 17-year-old accused of livestreaming and conspiring in the attack, and the overlapping criminal and civil cases are likely to raise policy questions about supervision, reporting protocols and the limits of voluntary mental-health care.
